Influence of short-interval intracortical inhibition on short-interval intracortical facilitation in human primary motor cortex.
Using the paired-pulse paradigm, transcranial magnetic stimulation (TMS) has revealed much about the human primary motor cortex (M1). A preceding subthreshold conditioning stimulus (CS) inhibits the excitability of the motor cortex, which is named short-interval intracortical inhibition (SICI). In contrast, facilitation is observed when the first pulse (S1) is followed by a second one at thresh...

27 Using the paired-pulse paradigm, transcranial magnetic stimulation (TMS) has 28 revealed much about the human primary motor cortex (M1). A preceding 29 subthreshold conditioning stimulus (CS) inhibits the excitability of the motor cortex, 30 which is named short-interval intracortical inhibition (SICI). In contrast, facilitation is 31 observed when the first pulse (S1) is followed by a secon...
متن کاملHeritability of intracortical inhibition and facilitation.
The present twin study investigates heritability of motor cortex excitability, measured by the paired pulse transcranial magnetic stimulation technique. Specifically, intracortical facilitation (ICF) and inhibition (ICI) and corticospinal excitability were tested in monozygotic (MZ), dizygotic (DZ), and unrelated pairs (UP). Robust ICF and ICI effects were found, with a higher similarity of MZ ...
متن کاملDissecting the Mechanisms Underlying Short-Interval Intracortical Inhibition Using Exercise
Recently, 2 physiologically distinct phases of short-interval intracortical inhibition (SICI) have been identified, a larger phase at interstimulus interval (ISI) 3 ms and a smaller phase at ISI 1 ms. While the former is mediated by synaptic processes, the mechanisms underlying the first phase of SICI remain a matter of debate. Separately, it is known that fatiguing hand exercise reduces SICI, ...
متن کاملEffects of short-latency afferent inhibition on short-interval intracortical inhibition.
Peripheral nerve stimulation inhibits the motor cortex, and the process has been termed short-latency afferent inhibition (SAI) at interstimulus intervals (ISIs) of ∼20 ms. The objective of the present study was to test how SAI interacts with short-interval intracortical inhibition (SICI) under different stimulation conditions. We studied 20 healthy volunteers. Surface electromyogram was record...
